Fortunately we don't have to think too hard about what they'd look like, because French artist Stéphane Massa-Bidal has designed a series of book covers for 10 of our favourite web services.

Massa-Bidal sells some of his designs on his online store, but these terrific book covers aren't available just yet. Perhaps if we all pester him enough he'll put them up? The Tumblr, Twitter and Flickr ones would look great on my wall. [Retrofuturs via Flickr via SuperPunch via Gearfuse]
